What are the center-to-center measurements for the D128454 Power Steering Cylinder?

You must confirm your mounting brackets match these dimensions before ordering to ensure the cylinder aligns with your steering linkage. Start by measuring the distance between your existing mounting points to verify they fit within these two specific ranges.

D128454 Power Steering Cylinder dimensions and hydraulic stroke requirements

The D128454 D84800 2X Power Steering Cylinder is a dual-cylinder setup, meaning these measurements apply to the pair of units provided in the pack. A cylinder is essentially a heavy-duty metal tube that uses hydraulic fluid to push a rod, moving the steering mechanism. Because steering cylinders must move through a specific range without hitting the frame, verifying the hydraulic stroke—the distance the internal piston head travels—against your available space is critical to prevent the system from bottoming out. We selected this model for our comparison because it serves as a primary replacement for several common part numbers, including 234447A1 and D84800. For example, a technician replacing a worn cylinder on a B series machine needs these exact center-to-center figures to ensure the new unit can reach full steering lock without mechanical interference.

What to Check Before Buying the D128454 Power Steering Cylinder

Before purchasing, verify these technical details to ensure the unit functions correctly in your specific configuration:

• Confirm your mounting orientation is either horizontal or vertical, as this determines the effective distance the cylinder can travel.
• Measure your current mounting plate thickness to ensure the cylinder seats flatly; a thin plate can cause the cylinder to tilt and wear out the seals.
• Verify that the 16-1/4″ to 23″ range accommodates your required stroke length without the piston hitting a physical obstruction.
• Check that your existing power steering hoses can be adapted to the specific port locations of the earlier B series compatibility.

Comparing the D128454 Power Steering Cylinder to Other Options

The D128454 Power Steering Cylinder is a specialized replacement part designed for specific compatibility with older machinery. Buyers who require industrial-grade actuators with high-duty cycles or specialized bore pressure ratings might look for alternatives that exceed these specific aftermarket dimensions. If your machine requires a different mounting orientation or a stroke length that falls outside the 16-1/4″ to 23″ range, you may need to source a cylinder with different internal specifications.

If you are working on a tractor, compare Massey Ferguson steering cylinder options to find the most compatible fit for your machinery.

If you need a replacement that matches the D84800 part number and fits an earlier B series machine, choose the D128454 Power Steering Cylinder.
